NetBSD version is a feature-to-feature re-implementation of GNU
gzip using the freely-redistributable zlib and this version is
expected to be mostly bug-to-bug compatible with the GNU
implementation.
- Because this is a piece of mature code and we want to make
changes so it is added directly rather than importing to
src/contrib.
- Connect newly added code to src/usr.bin/ and rescue/rescue
build.
- Disconnect the GNU gzip code from build for now, they will
be eventually removed completely.
- Provide two new src.conf(5) knobs, WITHOUT_BZIP2_SUPPORT and
WITHOUT_BZIP2.

he is the file's owner, he can't set set-gid bit.
POSIX requires to return 0 and clear the bit, but FreeBSD returns
EPERM for UFS in such case. For now do the same in ZFS.
This only works if there is no significant drift and all processors are
running at the same frequency. Fortunately, schedgraph traces on MP
machines tend to cover less than a second so drift shouldn't be an issue.
- KTRFile::synchstamp() iterates once over the whole list to determine the
lowest tsc value and syncs adjusts all other values to match. We assume
that the first tick recorded on all cpus happened at the same instant to
start with.
- KTRFile::monostamp() iterates again over the whole file and checks for
a cpu agnostic monotonically increasing clock. If the time ever goes
backwards the cpu responsible is adjusted further to fit. This will
make the possible incorrect delta between cpus as small as the shortest
time between two events. This time can be fairly large due to sched_lock
essentially protecting all events.
- KTRFile::checkstamp() now returns an adjusted timestamp.
- StateEvent::draw() detects states that occur out of order in time and
draws them as 0 pixels after printing a warning.
from the tsc.
- Set skipnext = 1 for yielding and preempted events so we don't show the
event that adds us back to the run queue. It used to be 2 so we would
skip the ksegrp run queue addition and the system run queue addition
but the ksegrp run queue has gone away.
- Don't display down to nanosecond resolution for scheduling events right
now. This can sometimes cause a division by zero.
Almost all regression tests are based on very flexible fstest tool.
They verify correctness (POSIX conformance) of almost all file
system-related system calls.
The motivation behind this work is my ZFS port and POSIX, who doesn't
provide free test suites.
Runs on: FreeBSD/UFS, FreeBSD/ZFS, Solaris/UFS, Solaris/ZFS
To try it out:
# cd fstest
# make
# find tests/* -type d | xargs prove
various types, as well as pipes and fifos for good measure. RELENG_6
currently passes all of these tests, but 7-CURRENT fails 0-byte writes
and sends on all stream socket types (and fifos, as they are based on
stream sockets).

to floating-point, the result is a quiet NaN. The current implementation
may return a signaling NaN, and the vendor has no plans for changing this,
for reasons explained in the comment I added.
mbuf is dropped, to preserve the invariant in the PR_ADDR case.
Add a regression test to detect this condition, but do not hook it
up to the build for now.

wildcard specifications. Earlier the only wildcard syntax
was "-j 0" for "any jail". There were at least
two shortcomings in it: First, jail ID 0 was abused; it
meant "no jail" in other utils, e.g., ps(1). Second, it
was impossible to match processed not in jail, which could
be useful to rc.d developers. Therefore a new syntax is
introduced: "-j any" means any jail while "-j none" means
out of jail. The old syntax is preserved for compatibility,
but now it's deprecated because it's limited and confusing.
Update the respective regression tests. While I'm here,
make the tests more complex but sensitive: Start several
processes, some in jail and some out of jail, so we can
detect that only the right processes are killed by pkill
or matched by pgrep.

This option enables building code that is licensed under Sun's CDDL.
The DTrace code is licensed that way, so by default it will get built
unless the WITHOUT_CDDL option is used.
There is another build toggle, NO_CTF, which turns off execution of
ctfconvert and ctfmerge in sys.mk, but this can't be implemented as
WITH_/WITHOUT because bsd.own.mk isn't included in all Makefiles and
sys.mk is included automatically by make.

implemented properly for a number of kernel subsystems. In general, they
try to exercise the privilege first as the root user, then as a test user,
in order to determine when privilege is being checked.
Currently, these tests do not compare inside/outside jail, and probably
should be enhanced to do that.

It is by no means expected to perform a complete test of the library
for correctness, but is meant to test the API to make sure libmp (or
libcrypto) updates don't totally break the library.
